Very big hostel. I felt it was a little overwhelming. I was only there for one night and had a bad experience before I even arrived (nothing to do with the hostel) One of the staff members was very nice to be making phone calls for me to relocate my lost bag.
Big rooms, lockers, and card entry.

This is not a party hostel. Tucked away in a side street but still really close to downtown, shops, restaurants and transport.
Rooms are not spacious and the room was hot, with only a small plug in fan.

This is the quality inn chain hotels. Great, huge room in a convenient location.
Walking distance to downtown. Very close to the space needle. Only negative was I extended my stay 3 nights and there was a bit of confusion with staff and the price of the extra nights were not honored.

Tina and Aldofo are lovely hosts. We extended out stay to 3 nights after falling in love with Cozumel.
The hostel is a bit out of the way of the town if getting around by foot, they can organize transport and diving. Private access to the beach was amazing. Highly recommended
